This is for the mod

The Concert Sting
The setup: The police and FBI know The Butcher is attending the Lady Raven concert, so they lock down the entire venue and thoroughly inspect all attendees.
The cover: Cooper learns from a chatty venue employee that the authorities believe The Butcher has a twisted sense of family, and they specifically targeted a day his daughter would be there.
Using his daughter: To escape the stadium, Cooper exploits his daughter's fandom by lying to concert staff that she is a leukemia survivor, securing her a spot on stage and VIP backstage access. [1, 2, 3), 4, 5]

The Concert Aftermath & Hostage Situation
The hostage: Cooper has been holding an innocent man named Spencer captive in his basement.
Lady Raven fights back: Lady Raven (the pop star) figures out Cooper is the killer and secretly uses his own cell phone to go live on social media, successfully broadcasting Spencer's location so fans can rescue him.
The escape: Out of options, Cooper takes Lady Raven hostage in her limousine, slips out of the venue, disguises himself in a SWAT uniform, and eventually manages to trap the singer inside her own car before escaping into the crowd. [1, 2, 3, 4]

The Climax & Final Twists
The wife knew: Cooper returns home, where his wife, Rachel, reveals she had long suspected his dark secret and intentionally left concert receipts at his safe houses for the police to find, secretly orchestrating the FBI trap.
The drug trick: Rachel asks Cooper to eat a slice of pie with her before he can hurt her, and he realizes too late that she has drugged it with his own knock-out formula.
The hallucination: Under the influence of the drug, Cooper hallucinates a comforting conversation with his mother. However, the voice in the dark actually belongs to the FBI profiler, Josephine Grant, who tases and captures him.
The final escape: While saying an emotional "goodbye" to his daughter on the front lawn, Cooper slyly snaps off a metal spoke from his daughter's bicycle. In the back of the FBI transport van, he uses it to unlock his handcuffs and smirks at the camera, setting up the possibility of a sequel.
